Consider the following scenario:
This issue occurs because the second response that is created from the DNS server cache is not authoritative. When you send a query to a DNS server for the first time, the server checks the records in its own authoritative zone. If you use a DNS plug-in feature, the DNS server sends the query to the plug-in. The result from the plug-in is cached in the DNS server cache for a while. If you query for the same records again, the response is created from the DNS server cache instead.
